IDTSExternalMetadataColumnCollection90 Interface

SQL Server 2005

Contains a collection of IDTSExternalMetadataColumn90 objects that represent the columns of an external data source.

Namespace: Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)
[TypeLibTypeAttribute(4160)] 
[DefaultMemberAttribute("Item")] 
[GuidAttribute("CC6D94F9-F447-4445-AB36-D786D7A21CB3")] 
public interface IDTSExternalMetadataColumnCollection90 : IEnumerable
/** @attribute TypeLibTypeAttribute(4160) */ 
/** @attribute DefaultMemberAttribute("Item") */ 
/** @attribute GuidAttribute("CC6D94F9-F447-4445-AB36-D786D7A21CB3") */ 
public interface IDTSExternalMetadataColumnCollection90 extends IEnumerable
TypeLibTypeAttribute(4160) 
DefaultMemberAttribute("Item") 
GuidAttribute("CC6D94F9-F447-4445-AB36-D786D7A21CB3") 
public interface IDTSExternalMetadataColumnCollection90 extends IEnumerable

A data flow component populates and uses this collection to validate the columns in its IDTSInputColumnCollection90 or IDTSOutputColumnCollection90 when the ValidateExternalMetadata property is false or when the SSIS Designer is in offline mode.

The collection typically represents the columns of an external data source used by a source or destination component. Use of the collection allows the component to perform validation without an expensive, time-consuming round trip to the source itself.

For more information about implementing external metadata columns in components see Implementing External Metadata.
